Hey all,
I was standing at NHG last night and looked down the tunnels and saw two signals at danger towards Hight Street Kensington. Then to my surprise it looked like the second of the signals cleared whilst the first one didnt.
I was wondering if anyone can tell me how many signals there are between the Notting Hill Gate starter and ED4 and their signal numbers please?
Many thanks! I hope you are all well!

Thanks buddy! Would you by any chance know which ones are visible from the NHG inner circle platform (excluding ofc A162)?

From memory of commuting from Notting Hill Gate several years ago, A158 and ED300 are both visible. ED3 is only just before High Street Kensington platform.
Depending on where the signals are mounted and the brightness of them, it might be that you saw the first of the two clearing - there is an optical illusion that can happen sometimes.

Thank you so much! A weird thing Ive noticed a number of times now is that often it looks like A158 is being held at danger (but its an Auto?) with ED300 being clear. I didnt think this would be possible since its an Auto, unless it too is approach controlled? (Im assuming ED300 is approach controlled based on its signal number). Which leads me to my next question. If a Train is at High Street Ken, Inner Circle, would a train waiting to enter the platform be held at ED300 or ED3? (Lastly, just from memory, there doesnt exist a RED3 does there?) Many thanks! |

ED300 is speed checked but if ED3 is cleared then ED300 automatically clears and no speed check is necessary like other speed control signals on the main. I have a feeling if a train is still in HSK platform then the train would be held at A158 until it moves off.
The way HSK works is that to clear ED3 you must select ED4rt1 or ED4rt2 first this is in the non safety circuitry and always catches out a new signaller when in push button mode on the programme machine.
I will check tomorrow what happens when a train is in the platform with A158 and ED300
No RED3 btw

A158 only requires the approach to the platform clear for the signal to be clear, if there is a train in the platform the signal will clear as normal
ED300 is to allow a train to go upto ED3 if its speed checked correctly when a train is sitting in the platform at HSK or reversing at ED14 (main line shunt just past ED4)
